1 Chemistry 108b Chemical Reactivity in the Environment Rachel Narehood Austin Dana 320 Class: Dana 119 M, W, F 8:20-9:20 Office Hours: Tuesday 4-5, Wednesday 7:30-8:15 in Dana 119 open session, Friday Laboratory: Monday 1:00-4:00, Tuesday 8:00-11:00 or Tuesday 1:00-4:00 Class web page on Lyceum Text: every class has assigned readings that are available on the class web page, 108b course pak, 108b lab manual Objective: to study and think about how and why atoms, molecules, and ions react, paying particular attention to chemical reactions that are critical in understanding chemical oceanography and environmental science Grading: Midterms (4) 40% Final exam 20% Lab 25% In-class case studies (5) 5% Homework, quizzes, reading notes 10% The final exam will be cumulative. You may bring three 5 x 7 notecards to the final exam or one 8 ½ x 11 sheet of notes. You will also be able to use a calculator and a periodic table. It may not be rescheduled make travel plans accordingly! You must pass the lab to pass the course. You must attend all laboratory meetings or have a written excuse from the Dean of Student s office for missing a laboratory meeting to pass the lab. Homework and Problem Sets will be assigned regularly and graded sporadically. No credit is given for late homework. You must be in class to hand in a homework assignment. Quizzes will be given on-line from time to time. You must complete the quiz by the assigned time to get credit for it but they will not be graded. Reading Notes on all assigned reading is required. These will be collected and graded sporadically. Attendance is critical for optimal performance. Attendance will be taken. Unexcused absence will prevent any end-of-semester curving of your grade. Final exam (CUMULATIVE!): Thursday April 16 th 8:00 am Academic honesty: It is expected that all students will work independently on exams and that no unauthorized information will be used to complete them. Lab reports must conform to standard academic rules for citing the work of others. If a breech of these policies is suspected, it

2 will be reported to the student conduct committee. If the student conduct committee finds the student guilty of the charges, the student will fail the course. Course Description: This course covers the same chemical content as any other section of CHEM108 taught at Bates College, and may be used interchangeably with Chem108A for any prerequisites. It differs from the CHEM108A sections in that it uses examples drawn primarily from chemical oceanography and environmental science to illustrate key chemical concepts. Guidelines for success: Read the assigned material before class and afterwards. Class time is designed to provide an overview of the material in each section. Use the available office hours to ask questions, discuss class material and ensure that you are staying on top of the work. I expect that you will spend approximately 4 hours on CHEM 108b outside of class for every 1 hour that we are in class together and that you will expect to do a lot of learning in that time. Do not plan on only coming to class and learning the course material by listening. That will not work! Laboratory: The laboratory provides an opportunity to actually explore the chemistry of marine environments. It will enable you to develop basic laboratory skills that are used in a number of different scientific disciplines. The methods we will use in the lab come from standard analytical procedures and are often used to monitor water quality. If you get a job monitoring water quality at some point, you will likely use at least some of the techniques that we will learn in lab. Lab meets every week, beginning the first week of class. You must arrive in lab on time and you must attend every scheduled lab class. Absences must be accompanied by a Dean s excuse and arrangements must be made with the laboratory instructor or myself to make up any missed work. You must come to lab the first day with safety goggles, a lab manual and a lab notebook. CLASS OVERVIEW Overview of tools and topics At the end of a chemical reaction, what is present?
